The GTN micromechanical fracture model is frequently used to predict the ductile fracture. This model is based on the microscopic mechanism of void nucleation, growth and coalescence in ductile material. GTN model includes many parameters that need to be precisely calibrated in order to obtain the maximum accuracy. In this study, an indirect approa...
In this paper, the effect of Ti-rich areas on the fracture of NiTi alloys has been studied. To carry out this investigation, a series of experimental tests, as well as numerical analyses are conducted. In the experimental plan, NiTi smooth and notched bars with various notch sizes are subjected to tensile load until fracture. Moreover, the correspo...

The feasibility process of public construction projects is under the influence of stakeholders, who give direction to public resource allocation. Therefore, the analysis of stakeholders in this process is critical. An inductive qualitative approach was adopted using the grounded theory method to provide a theoretical explanation of stakeholders’ be...
Traditional methods of summarization are not cost-effective and possible today. Extractive summarization is a process that helps to extract the most important sentences from a text automatically, and generates a short informative summary. In this work, we propose a novel unsupervised method to summarize Persian texts. The proposed method adopt a hy...
Iran is one of the endemic areas of Dirofilariasis, and also one of the most important zoonotic infections. Dirofilaria immitis causes a severe and fatal disease called heartworm disease in dog. It also produces pulmonary nodules in humans. The worm is to be investigated as a potential infection of humans and animals in various provinces in Iran. I...
In this research, the ductile fracture of ultra-fine-grained copper was investigated. Ultra-fine-grained copper was produced using equal channel angular pressing process. During this process, the average grain size of the copper specimens decreases. Experiments have shown that stress state has significant effect on fracture behavior and should be i...
Introduction: It is crucial to find ways to improve the durability of learning in clinical units. One of these methods is team-based learning (TBL). This learning method is active and students must study the subject before the session.
Objective: This study examined TBL and compared it with conventional lecture method (LM) in an educational approa...
This study has been conducted to investigate the voids behavior in shape memory alloys (SMAs) up to fracture. Two kinds of NiTi samples with different geometries are studied including a smooth thick sheet which includes the phase transformation and a smooth round bar without phase transformation. The SEM images are utilized to observe the voids and...
In this paper, the ductile fracture of ultra-fine grained copper, purity 99.7%, processed by equal channel angular pressing (ECAP) is considered. To simulate the ductile fracture, a phenomenological ductile fracture model is developed by incorporating the effect of the grain size refinement during ECAP process. The implemented damage plasticity the...
In this study, a constitutive model is proposed to investigate the pseudoelastic-plastic behavior of the shape memory alloys, SMAs, up to fracture. The proposed model is based on the Boyd and Lagoudas phase transformation model which is extended to take into account the plastic deformation and the fracture behavior of the SMAs by using the Gurson-T...
In this paper, the high cycle fatigue life of ultra-fine grained copper, purity 99.7%, processed by equal channel angular pressing (ECAP) has been considered. To produce the ECAPed specimens, the associated die set was designed and manufactured. Mechanical properties of the ECAPed material were evaluated by standard tensile tests. Moreover, the hig...
Background: Shalom Schwartz defined the core values "as desirable, trans-situational goals, varying in importances that serve as guiding principles in people's lives". The value types proposed by Schwartz were: power, achievement, he-donism, stimulation, self-direction, universalism, benevo-lence, conformity, tradition and security. This study de-s...

... Hall et al. (2015) claim that stakeholder analysis is helpful to policymakers and managers to be informed about the political environment surrounding a decision before its implementation. Sarhadi et al. (2021) argue that stakeholder analysis gives marginalized stakeholders greater capacity to participate effectively in the decision-making process. These studies demonstrate the importance of understanding stakeholders that are critical for success. ...

... Various studies have reported coinfection of microfilarial species with Anaplasma spp., Ehrlichia spp., and Leishmania spp. [2,[4][5][6][7]. These pathogens have the potential to infect humans, so canine vector-borne diseases are an important group of zoonotic illnesses for veterinary and public health [8]. ...
... Ductility generally increases at lower stress triaxiality with compressive stress when void growth and connection is the fracture process [18]. Because of the unique deformation mode of UFG materials, the effect of triaxiality stress on ductility could be stronger in UFG materials using ECAP than the coarse-grained materials [19]. ...

... Results show that the induced residual stress, plastic strain, and damage fields can be predicted. The fracture analysis of shape memory alloys based on GTN model's voids nucleation/growth in martensite and austenite phase has also been studied recently [22,23]. Bahrami et al. [23] proposed a constitutive model to investigate the pseudoelastic-plastic behavior of the shape memory alloys, SMAs, up to fracture. ...

... Electrolytic Tough Pitch (ETP) copper is a high purity copper (>99.9 wt%) frequently used for the transmission of electrical energy due to a low resistivity (Copper Development Association Inc.). The ductile damage and failures of pure copper have been object of different studies [2,3], as well as the impact of strain rate and temperature [4]. The material can in fact be subjected to creep deformation even at temperatures at and slightly above room temperature, if the stress level is sufficiently high to activate relevant mechanisms [5]. ...
... Nevertheless, a micromechanical model can solve this confused issue [5]. On the basis of the micromechanical theory, Gurson-Tvergaard-Needleman (GTN) model was developed [6], and until now it has been widely applied to describe the damage behaviors of materials, such as in aluminum alloy [7], titanium alloy [8], shape memory alloy [9], high strength steel [7], etc. Once the GTN model was figured out and planted into the finite element (FE) software, the volume fraction of microvoids can be derived in real time during a deforming process. ...
... This interest is due to the significant improvement that nanostructured materials present compared to their original state. Bulk nanostructured materials processed by methods of SPD significantly improve the mechanical properties like tensile (Limooei et al. 2018), compressive (Liu et al. 2013), and shear strength (Asadi and Kazeminezhad 2017), fatigue resistance (Khalilpourazary et al. 2019) as well as superplastic behavior under specific conditions (Furukawa et al. 2000). One of the techniques of SPD is DECLE which is a combination of equal channel angular pressing (ECAP) (Ghazani et al. 2019) and multi-directional forging (MDF) (Cherukuri and Srinivasan 2006). ...
